The various scores divide the thickness adapted to liealong the inner surfaces blank into lateral Walls including side walls`II 30 of the walls from which the flaps issue. and I1 and end walls I8and I9.

A

otner objects of the invention reside in the tabs 42 arof suphdimensions and the position novel combination and arrangementof partsand of the score 4I 1s such that the upper edge of in the details ofconstruction hereinafter illusthe tab 42 when folded upon the 1nter1orof tlfe rated and/or described. box, extends to within a .distance ofthe score 55 it less than the width oi the elongated portions 3d and S5.

In the construction of the box, the two edges and tl of the blank l@ arejoined together with a suitable strip of fabric or some other suitablematerial indicated at d. When the box is to be erected, the box isshifted into rectangular form and the extensions 2t, 2l, 23 and 29,which serve as flaps, are folded inwardly and glued together, -forming abottom for the box. Thereafter the extensions Z and Ztl are folded alongthe scores ll, 32 and 3i to cause the portions 3d and 35 to lie adjacentone another and to extend inwardly into the box from the fiap'33. Thetwo portions 34% and 35 form a flange which,l I have indicated by thereference numeral 38 in Figs. 2 and 3 and which issues inwardly into thebox and lies along the inner surface of the walls iii and i9. After thebox has been lled, the flaps 22 and 265 and the extensions 23 andd,which also serve as aps, are folded inwardly and the parts gluedtogether. If desired, glue may be placed between the two elongatedportions til and 3E and the portion 315 also glued to the inner surfaceof the wall from which it issues. Score 3l forms a hinge for the ap 33and the particular wall with which it is connected when the flange 38 isglued to wall i3, while either score 3i or ii may serve as a hinge whenflange 3S is free from said wall. The various flaps, upon being foldedinto overlying position, are glued together andthe box becomes closed.In the handling of the box, the tabs t2 are forced inwardly by thefingers and the fingers directed upwardly to swing the tabs intoposition to overlie the flanges 3B. This forms hand holds b y means ofwhich the box may be lifted. The box may then be handled in thecustomary manner and the fingers held against the said tabs to cause thesame to occupy the desired positions. While so disposed,l the flanges 38are held adjacent the walls from which they issue and serve to reinforcethe said walls Aand to transmit the stresses from the load to thefingers of the user.

My invention is highly advantageous in that an extremely simple andpractical construction is provided whereby boxes for use in holdingrelatively heavy articles mayfbe constructed entirely from paper. Withmy invention, suitable reinforcing means are provided at the hand holesso that breakage of the box is prevented and the stresses at the weakerportion of the box greatly reduced. My invention can be constructed withordinary machinery now available for the construction of the boxes andwithout appreciable additional expense.

Changes in the specific form of my invention, as herein disclosed, maybe made within the scope of what is claimed without departing from thespirit of my. invention.

Having described my invention, what I claim as new and desire toprotectl by Letters Patent is:

l. A box comprising lateral walls and a bottom connected therewith, aclosure ap extending outwardly from the upper end of one of said lateralwalls, said flap having a fiange projecting therefrom and when theclosure ap is in closing position being adapted to extend downwardlyinto the box in juxtaposition with respect to the lateral wall fromwhich said flap issues, and a tab on said denoted lateral wall adaptedto overlie said flange.

2. A box comprising lateral walls and a bottom connected therewith,closure naps extending from two opposite walls of the box, said closurenaps having flanges projecting therefrom and adapted tooverlie the innersurface of said walls when the fiaps are in closing position, and tabsissuing inwardly from said Walls and overlying said flanges.`

3. A box constructed of paper and comprising lateral walls and a, bottomconnected therewith, a closure flap having a hinge connection to one ofsaidlateral walls the material from` which said nap is constructed beingdoubled back to form a. flange of double thickness at said hingeconnection adapted to overlie said denoted wall upon the interiorthereof, and a tab struck out of said denoted wall and adapted tooverlie said flange and to form a hand hold, said flange aiding indistributing the load from the bottom to said hand hold. I

4. A box constructed of paper and comprising lateral walls and a bottomconnected therewith, an extension formed on the upper end of one of saidwalls, said extension being formed with a score extending along theupper edge of said wall and with two other scores parallel therewith andspaced apart to form two transversely extending elongated portions ofequal width and a flap therebeyond, said extension being folded alongsaid scores to cause said elongated portions of the extension to lie injuxtaposition and form a flange of double thickness issuing from saidflap at the first-named score and adapted to overlie the inner surfaceof said wall, and a tab struck out of said denoted wall ata localitybelow said flange and connected to said wall by a score parallel withthe upper edge of said wall, and situated immediately below said flange,said tab being adapted to be folded inwardly into the box in a positionoverlying said flange.
